I refer the minister to the Government’s ongoing water restrictions - (1) What is the estimated annual sustainable yield of ground water for the Perth region? (2) Is it the Water Corporation’s understanding that the sustainable yield is the amount that can be extracted without causing degradation to the environment? (3) What is the current estimate of total annual ground water extraction in the Perth region? (4) Does the Water Corporation plan to access the portion of Perth’s sustainable yield of ground water that remains unused; and, if not, why not? (5) What would be the estimated increase in water consumption for 2003-04 if households were permitted to use water sprinklers on one extra day per week? Hon NICK GRIFFITHS
